Changelog

This page documents the complete version history and release log of the Rotifer Protocol reference implementation (@rotifer/playground).

Version overview: Rotifer has 7 historical version series with 20+ releases. Full version list: v0.1.0 (initial), v0.2.0 (Arena), v0.3.0 (WASM compilation), v0.4.0 (cloud), v0.5.x (P2P + reputation), v0.7.x (stabilization), v0.7.9 (trust shield), v0.8.0 (Iron Shell), v0.8.6 (current public release). Detailed changelog for each version below.

v0.8.6 (2026-04-21) — Current (CLI Runtime Bugfix + Native Addon Distribution)

Four CLI runtime bugs fixed, plus the first release shipping prebuilt native binaries across all major platforms.

Javy async Gene fix — async express() genes no longer crash with “Pending jobs in the event queue”; the compile step now detects async usage and reports a clear error
Compile cache fix — rotifer compile now detects source file changes and recompiles; previously a stale gene.wasm was reused silently even after editing index.ts
irHash serde fix — genes with an irHash in phenotype.json no longer fail on the native (wasmtime) execution path; the hex-string/byte-array mismatch is resolved
WASM sandbox fuel fix — default fuel raised from 1M to 500M, memory to 256 MiB, timeout to 60s; Javy/QuickJS genes no longer hit “fuel exhausted” on trivial workloads
Native addon distribution — prebuilt .node binaries now ship via platform-specific packages (@rotifer/playground-darwin-arm64, -darwin-x64, -linux-x64-gnu, -win32-x64-msvc); npm install automatically picks the right binary — no local Rust toolchain required

v0.8.5 (2026-04-08) — Ecosystem Alignment

First release where CLI, MCP Server, VS Code extension, docs, and install snippets all present a single coherent version number to users.

Unified install experience: npm install -g @rotifer/playground, npx @rotifer/mcp-server, and the VS Code extension all point to the same v0.8.5 surface — no more version mismatch between tools
Skill→Gene migration path documented: the rotifer wrap --from-clawhub workflow and Skill migration guide are now part of the public docs
CLI update notifications: the CLI now alerts users when a newer version is available
IDE distribution cleanup: plugin families and marketplace metadata are consistently versioned across VS Code Marketplace and Open VSX

v0.8.0 (2026-02-17) — Iron Shell

Security hardening, P2P Protocol RFC, Epoch automation, AI documentation assistant, and 30+ deliverables.

Supabase deep security audit: Full attack surface validation across Hybrid Gene gateway, WASM upload, Edge Functions, Reputation RPCs, Badge Worker, V(g) scanner, Gene Registry, MCP call stats
WASM sandbox escape testing: 15+ security tests covering memory OOB, infinite loops, host function abuse, resource exhaustion, malformed IR
P2P Protocol RFC: Complete design document — transport (QUIC/libp2p), discovery (mDNS + Kademlia DHT), GossipSub messaging, Sybil/Eclipse protection, Cloud binding collaboration
Security Checklist mechanism: Reusable version-level security checklist template integrated into CI and release flow
Epoch automation: pg_cron daily reputation computation + monthly decay with idempotent compute_all_reputations() RPC
ContributionMetrics: Anti-manipulation ready contribution tracking (gene_invocation_log, gene_contribution_metrics)
LLM-Native Gene standard: Prompt Gene + Guard Gene phenotype definitions (ADR-084)
Evolution API Level 1.5: Gene recommendation + Arena observability REST endpoints
AI documentation assistant: RAG-powered chat on rotifer.dev with rate limiting, content filtering, caching, and analytics

Infrastructure resilience: GitLab→GitHub CI migration, Forgejo migration preparation, Cloudflare Pages deployment pipeline

v0.7.10 (2026-03-24)

Security hardening, WebMCP expansion, and China market readiness.

Schema Compatibility Check: Static type checking for Seq pipeline — validates output→input schema alignment with PASS / UNCHECKED / FAIL diagnostics
Try Fallback Error Propagation: Try operator now passes structured {error, original_input} to fallback genes instead of bare input
WebMCP Phase 1: 10→14 tools — 4 new write-enabled (L3) tools: set_gene_visibility, request_arena_evaluation, create_gene, update_gene_metadata with auth + confirm dialog
Path Traversal Guard: rotifer init now rejects project names containing ../ sequences
China Network Guide: Chinese getting-started docs with cnpm mirror install and Supabase latency notes
CI Pipeline Hardening: Fixed deploy configs, Node 20 compatibility, resilient network-dependent tests

Versioning Policy

The Rotifer Protocol follows Semantic Versioning:

Major (1.x): Breaking protocol changes
Minor (0.x): New features, backward-compatible
Patch (0.0.x): Bug fixes and improvements

Current status: Pre-1.0 — the protocol is under active development. APIs may change between minor versions.
